The New York-based media company, which also owns HarperCollins Publishers and many newspapers in the U.K. and Australia, swung to a loss of $730 million from a profit of $10 million a year earlier. Results were dragged down by $1.13 billion in impairment and restructuring charges primarily tied to its pay-TV service in Australia and a coupon company that has been sold.

Revenue fell to $2.27 billion from $2.46 billion for the quarter ended March 31. The slide stemmed in part from the depreciation of the Australian dollar and British pound against the U.S. dollar, a weak print-advertising market and lower subscription revenue at Foxtel, its Australian pay-TV service. The coronavirus pandemic weighed on results in the latter part of the quarter.

“We are operating in a different, difficult time,” said Chief Executive Robert Thomson. He said that despite the onset of the coronavirus and adverse currency movements, profitability was relatively stable at the company, thanks primarily to significant digital-advertising and subscriber growth at Dow Jones, whose properties include the Journal, Barron’s and MarketWatch.

News Corp said the Journal experienced a sharp increase in subscriptions since the start of the pandemic. In the past week, the Journal reached approximately 3 million total subscribers, a record—over 2.2 million of which were digital-only subscribers.

During the quarter, News Corp continued to sell assets to simplify its business structure. On Thursday, it said it had completed on May 5 its previously disclosed sale of News America Marketing, a coupon-publishing unit, to the private-equity firm Charlesbank Capital Partners. In January, News Corp sold Unruly, a video-advertising platform, to Tremor International Ltd.

As the impact of the coronavirus pandemic deepened, News Corp laid off hundreds of staffers in Australia and the U.S., including at News Corp headquarters in New York; at the New York Post; and at Move Inc., the operator of realtor.com, according to a News Corp spokesman.

Mr. Thomson said the crisis was also affecting executive compensation. He said he would forgo 75% of his cash bonus for the current fiscal year, and that Executive Chairman Rupert Murdoch would forgo his entire cash bonus. The bonuses of other senior executives will be reduced by at least 20%, and the board is reducing its cash compensation, Mr. Thomson said.

News Corp’s largest unit, the news and information-services business that includes Journal parent Dow Jones, the Times of London and New York Post, reported a 7.7% decline in revenue to $1.13 billion, reflecting a $25 million, or 2%, negative impact from foreign-currency fluctuations.

Revenue at Dow Jones increased 5%, while revenue at News Corp Australia fell 14% and revenue at News UK declined 9%. Ebitda rose 15% to $75 million, which the company attributed to a higher contribution from Dow Jones, lower losses at the New York Post and the absence of losses resulting from the sale of Unruly.

Advertising revenue for the news unit declined 14%, while circulation and subscription revenue rose 1% overall. At Dow Jones, circulation revenue was boosted in part by a 20% increase in digital subscribers, as well as subscription-price increases. Dow Jones’s advertising revenue fell 2% in the quarter due to an 18% decline in print advertising, which was partially offset by a 25% growth in digital advertising.

The Journal averaged 2.041 million daily digital subscribers for the quarter, up from 1.929 million in the quarter ended Dec. 31. That is a gain of 112,000 subscribers, compared with an increase of 75,000 subscribers in the previous quarter.

Looking ahead, News Corp said that the impact of the pandemic would be more significant in the next quarter. Advertising revenues fell more than 20% at Dow Jones in April, including a modest decline in digital advertising. Advertising revenue at News Corp Australia and News UK fell more than 45%, including a negative impact from foreign-currency fluctuations.

On the plus side, the company saw “strong growth” in digital subscribers across its leading properties in April.

Earlier this week, Almar Latour, publisher of the Barron’s Group, was named CEO of Dow Jones and publisher of the Journal, succeeding William Lewis effective May 15.

Revenue at News Corp’s book-publishing unit declined 2.1% to $412 million, reflecting in part the negative impact from foreign-currency fluctuations and “difficult” comparisons to the prior year. Ebitda rose 3.8% to $55 million.

The digital real-estate business, which includes Move Inc., reported a 4% decline in revenue to $261 million, reflecting foreign-currency fluctuations and the impact of the coronavirus pandemic, and a 1.4% gain in Ebitda to $74 million.
